FIELD

Disclosed embodiments of the present invention relate generally to the field of data processing, and more particularly to automated change approval in data processing environments.

BACKGROUND

Data processing devices are deployed in many different configurations and are used for many different applications in a variety of data processing environments. In some configurations, data processing devices may be grouped for various reasons. For example, using servers as illustrative data processing devices, servers may reside together in a server farm. A server farm may streamline internal processes by distributing the workload among the individual servers of the farm and may expedite computing processes by harnessing the abilities of multiple servers. Groups of servers in server farms may be identical, or similar in certain operational respects, for a variety of reasons, including mirror servers, back-up servers, etc. While multiple servers may initially commence operation with identical, or similar, operational states, varying changes may occur, either by design, inadvertently, or otherwise, among the multiple servers. Similar situations may arise among a wide variety of data processing devices, including but not limited to switches, routers, and other networking devices of the like.

Such hashes may make use of any number of past, present, and future hashing algorithms consistent with the principles of an embodiment of this invention. Such hashing algorithms include, but are not limited to, MD5 (Message Digest 5), SHA-1 (Secure HASH Algorithm), and HAVAL (Hashing Algorithm with Variable Length).

In various embodiments, the one or more modules may facilitate definition in digital form of one or more responses to one or more detected differences during said automated comparison of the second and third memorializations to the first memorialization. In some embodiments, the one or more responses may include a no-action automatic approval response. For example, in some embodiments, a no-action automatic approval response may be applied in cases where a difference, or “violation,” in either the second or third memorializations matches a difference, or “violation,” in the first memorialization. In some embodiments, a no-action automatic approval response may be applied in cases where certain differences have been pre-approved, such as, for example, for acceptable differences known to arise on a certain data processing device. In some embodiments, a no-action automatic approval response may be applied in other cases.

In some embodiments, the one or more responses to one or more detected differences during said automated comparison of the second and third memorializations to the first memorialization may include an automatic remediation or alert response to a detected difference. For example, in some embodiments, an automatic remediation response may comprise of making a change to the second data processing device, where said change had been made to the first data processing device. This may occur when the first memorialization indicates such a change had been made to the first data processing device and the second memorialization indicates that such a change had not been made to the second data processing device. In some embodiments, where such a change had been made to the first data processing device and not to the second data processing device, an alert response notifying a user of such a detection may occur. In various embodiments, other responses may comprise either automatic remediation or alert responses to detected differences.
